To (din/71 0712, it UI/III I/ concern: I

Be it known that 1, GEORGE B. Essex, a citizen of the United States of America, re-

, siding at Detroit, in the county of Wayne and operation, the flow of oil being controlled by tie engine. It is also an object of the inventionto so construct the device that any leakage around the sight tubes may be quickly and easily remedied and so as to especially adapt the sight-feed to be readily attached to the dash-board or similar part of the vehiclein such a manner as to conceal the pipes and connections leading thereto.

A further object of the invention is to provide a very simple, compact and efiicient device presenting a neat appearance and embodying certain other new and useful features in its construction, arrangement and combination of parts, all as hereinafter more fully described, reference being had to the accompanying drawings, in which Figure 1 is a view illustrating the manner in which'the sight-feed and its su ply tank are connected with each other anti with the engine; Fig. 2, is a front' elevation of the sightleed; Fig. 3, a transverse vertical section of the same on the line 20-31 of Fig. 2; and Fig. 4, a vertical section on the line l -y of Fig. i).

As shown n Fig. 1, A is the multiple sightfced shown secured tothe dash-board B or similar partbf the automobile. ()re resents the engine and D the oil supply tan which is connected to the sight-feed by a supply pipe I? and with the crankcase of the engme by a pipe F, said pipe F leading from the crank case to the top of the tank so that when the engine is running the air e01- pressed in the crank case by the engine piston will be forced through the pipe into the oil tank and put a pressure on the oil which will thus be forced up through the supply pipe to the sight-feed, from which is passes into the tubes G leading to the several bearings or parts to be lubricated.

hen the engine is stoppcdfthc pressure in i the oil tank falls at once, thus stopping the flow 0f .oil'therefrom to the sigl'it-feed, but in order-to prevent the oil contained in. the sight-feed and adjacent end of the.

supply pipe from passing on and flooding.

the bearings, I make the supply pipe of a comparatively large diameter so that its capacity is greater than that of the passage in the sight-feed and locate the tank some distance from and below the sight-feed, preferably near the engine cylinder where it will be kept warm, and therefore when the pressure is taken from the oil in the tank,-the weight'of the body of oil then contained in the supply pipe will cause the oilto flow rapidly back toward the tank and thus form a suction which will draw all of the oil from the said passage and at once stop the llow to the bearings. v

The sight-feed A consists of an u per cast head 1 and a lower cast head 2 eacli formed with a series of sockets to receive-the ends of glass feed tubes 3 with packing rings 4 interposed between the ends of said tubes and the bottoms of the sockets, and screw-bolts 5 extending through openings in the upper head between the tubes, engage screwthreaded openings in the lower head and draw said heads toward each other to firmly clamp the tubes between.

Feed nipples 6 formed integral withthe head 1, pro ect downward therefrom in the axis of each sight-tube, and opposite each nipple the head is bored inward from the upperside to form a chamber? and said nipples are bored verticallytoform discharge ducts 8 leading from said chambers. Each of the chambers 7 is closed by a valve fitting 9 screwed into its upper end, and-through each fitting passes a screw threaded stem 10 having a needle point 11 at its lower end to.

project into theupper end of the duct 8 and control the flow of oil therethrough. Each fitting is also provided with a'packing nut 12 on its outer end through which its valve stem projects to prevent leakage around the same.

These chambers 7 communicate with each other through a assage 13'formed by boring longitudinally. tlirough the head and then plu ging the ends of thebore, and this passage ainf' the chambers are supplied with oil through a stem 14 formed integral with the head and extending horizontally outward 5 The lower head 2 is formed with horizontally extending stems 16, one for eachsight- ,tube, extending rearwardly from the head and externally screw-threaded to receive a coupling nut17 by means of which the tubes G are secured theretoand' also to receive a binding nut 18 adapted to engage the rear side of the dash-board B, which is provided with a series of holes to receive the stems, and. securely clamp the heads against the face of said dash. The lower head is bored vertically downward in the axis of each sight-tube to meet the bores of the stems 16 and form' the discharge passages from the sight-feed, and a downwardly extending flange or apron is provided along the front and ends of'the lower head to form a finish and hide the stems. nut 18 may also lee-provided on the stem 14 which also extends through an opening in the dash, to further secure the sight-feed in place, and instead of boring out the chambers 7 in thenpper head and screwing in the fittings 9, the head may be cored outand said fittings formed integral with the head.

By forming the heads with the stems which project laterally therefrom throughv the .dash and form themeans for securing the sight-"feed dash, said feed is firmly held andeall pipgsj tubes, and connections are concaledby the'dash, makinga very neat and cheap construction; and by making two separate heaziswith recessesto receive the sight-tubes and drawing these heads into contact with the packing by bolts, a very simple and practical construction is secured as any inaccuracy vin-the heads ortubes is compensated for by the packing and the forcing of the heads into firmer contact therewith, and as the construction is such that any person however unskilled will readily see that bytightening the screw bolts leakage will be stopped: Y

Having thus fully described my invention, whatI claim is:- I I 1. The combination of a sight-feed having t a series'of sight-glasses and discharge passages leadin therefrom, a series of externally screw-threaded stems forming a continuation V of said pass ges and extending laterally from $5 thesight-fee to Project through openings in a dash-board or similar support, tubes connected to the ends of said stems, and nuts on the stems to engage the dash-board andsecure the sight-feed thereto.

2,;The combination of a head having a longitudinal" oil passage, a stem formed inte- A binding or securing .gral with said head and extending laterally therefrom and provided with a passage com' municating with the passage in the head, a supply pipe connected to said stem, a lower head provided with. discharge passages, a series of sight-tubes interposed between said heads, a series of stems formed inte ral with the lower head andextending laterally therefrom with passages communicating with the discharge passages, tubes secured to the ends. of said screws or stems, and means on said stems for securing the same within openings in a dash-board with.the heads -in contact with the face of said board. I

3, The combination of a head formed with a longitudinal passage for oil and with ducts leading from said passage for the discharge of the oil therefrom, a series of needle valves to control the flow of oil through said ducts, an externally screw-threaded stem formed integral with said head with a passage com-' municating with the passage therein and extending laterally from the rear side of said head, a lower head formed with a series of discharge passages, sight-tubes interposed between said heads, a series of stems formed integral with the lower head with passages communicating with the discharge passages and extending laterally from the rear side of the head,there being a downwardly extending flange on the front side of said lower head. 4, The combination of a head formed with chambers and a longitudinal passage con necting said chambers and recesses in its lower side, a series of nipples extending downward from -the lower side of the head in the axis of said recesses and providedwith ducts communicating with the chambeis, valve fittings screwed into the upper ends of said chambers, valve stems extending through said fittings and provided with needle points to engage the said ducts, a stem formed integral with said head and extended laterally from the rear side thereof, a lower head formed with a series of recesses and discharge passages leading from the axes of said recesses, sight-tubes engaging the recesses in said heads, externally screw-threaded stems having passages communicating with the discharge passages and extending laterally from the rear side of said lower head, nuts on said stems, there being a flange extending downward from said lower head at the front side thereof, 7.

In testimony whereof I aflix my signature in presence of two witnesses, 1 p r GEORGE ESSEX.
